This. invention relates to new anduseful improvements in. a combinedwriting and eradicati'ngimplement, and, more. particularly, the aim isto provide a novel and valuable duo-fountain implement whereinonefountain serves a writing point and another fountain serves aneradicating point; the present. utilityespecially in mind being theprovision of an improved stenographic pen and eradicator.

According to the present invention a single article is provided, whichmay closely resemble an ordinary fountain pen, and which incorporates asingle barrel having at one end a writing point. and at its. oppositeend an eradicator point. Both fountains are inside said one barrel, butthe barrelis separable into a plurality of sections ata. point,intermediate its ends to allow convenient refilling when such arefilling is required. Also, desirably, the new implement is providedwith two readily removable caps, one at each end, and each for coveringone of the points when the. latter is notin use. H

A featureof the invention is the subdivision of the. barrel into threereadily separable sections, these being preferably threadedly connected;with the middle section a rather short or ring-like section, and whichmay be uncoupled from the other two sections, thereby to free thesection having the eradicator point from the other two sections. In thislatter connection. means are provided whereby the eradicator fountainmay be readily refilled. Another feature of the invention isthe'provision of a bodily removable closing valve member for the fillingend. of the eradicator fountain, which valve member, in combination witha cooperating. part carried by the section having the ink fountain andfurther in combination with a shaped internal portion of' the ringsection, restrains the fluid in the fountain last-named from accidentalspill therefrom.

For further comprehension of the invention, and; of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 elevationally shows a now favored embodiment of the newimplement, with both caps applied to the barrel.

Fig; 2 is a similar view, but partially broken away and partially insection, with both, the caps removed.

Fig. 4 shows the implement elevationally, with both caps removed as inFig. 2, and, furthenwith said ring section and the section forcontaining the eradicator fluid both removed. Y

Fig; 5 elevationally shows merely the section for containing theeradicator fluid, with the already mentioned valve member left inplace.

Fig. 6 is an enlarged top plan view of said valve member. Fig. 7 showsthe same in side elevation. Referring to the drawings-more in detail,the barrel, as a whole designated It), incorporates three threadedlyconnected sections IZQM and I5; the latter being the ring section.Section l2 at its tip carriesa writing point l6, which may be of thelong familiar split nib type or of the rolling ball type recently cominginto rather wide use. The section [4 at its tip carries a suitableeradicator point I1, which also may be of the said split nib type or ofsaid rolling ball type.

The ring section l5 has an axial bore there through which centrally isof slightly less diameter, as indicated at (8, than its upper and lowerportions, where said bore is threaded as shown at [9 and 2D. The threadI9 is for matching an external thread on a reduced lower extension 2| ofthe section l2, and the thread 20 is for matchingan external thread onthe reduced upper extension 22 of the section 14.

The ink fountain for the point It is within a cavitation 23 in thesection 12; and the fountain of eradicating fluid for the point I! isconstituted by a cavitation 24 in the section 14. I

Any desired means for refilling the said ink fountain may be included;but, as herein shown, a familiar type of suction efiectuating rockerarm25 for use in such refilling is indicated in Fig. 2.

Projected below the lower end of the extension '2! depending from thesection I2, and suitably there anchored, is a substantiallyhemispherical projection 26.

At the upper end of the reduced extension 22 at the top of the sectionM, the filling opening for the-cavitation 24' is shaped to provide avalveseat for fluid-tight coaction, with a bodily r'emovable valvemember 29, which latter has a central depression 30 in its disk-like topportion 3!, this. depression forseating the projection 26 when the partsare coupled as shown in Fig. 2. Then, as will be noted, said projectionis received in the hollow portion [8- of. the ring section 15,

as is also the said portion 3| of the valve member 23.;

In addition to the barrel I0, the new implement is provided with a pairof separately readily removable caps 32 and 33; with, of course, the cap32 to be temporarily removed when writing is to be done and the cap 33to be temporarily removed when eradicating is to be done. As isconventional, the section I2 may be provided at a suitable pointthereon, as at 34, with a tiny air-admission orifice. A similar orificemay be provided at a suitable point on the barrel II; but, as hereinshown, the air-admission means comprises an orifice 35 through the ringsection l5 opposite the recess II, and, in combination therewith, asuitably placed orifice, as indicated.

at 36, slantingly passing through the valve member 29. Thus, free use ofeither of the points l8 and I! cannot be hampered by trapped air in itsfountain.

In order to refill the cavitation. with eradicator fluid, it is merelynecessary to unscrew the section H, and lift from its seat the valvemem-,- ber 29, and them supply the said fluid as by the aid of a glassmedicine dropper. Y

While I have illustrated and described the preferred embodiment of myinvention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.
